in the study of the church of S. Irene, and I thank Mr. George personally for the cordial readiness with which he consented to allow me even to anticipate his own monograph on that very interesting fabric. It is impossible to thank Professor Baldwin Brown3 of the University of Edinburgh, enoughj for his unfailing kindness whenever I consulted him in connection with my work. Nor do I forget how much I owe to J. Meade Falkner, Esq.j for kindly undertaking the irksome task of revising the proofs of the book while going through the press.
I cannot close without calling attention to the brighter day which has dawned on the students of the antiquities of Constantinople since constitutional government has been introduced in the Ottoman Empire. Permission to carry on excavations in the city has been promised me. The archaeology of New Rome only waits for wealthy patrons to enable it to reach a position similar to that occupied by archaeological research in other centres of ancient and mediaeval civilizations. But the monuments of the olden time are perishable. Of the churches described by Paspates in his Byzantine Studies^ published in 18773 n^ne have either entirely disappeared or lost more of their original features. It was no part of wisdom to let the books of the cunning Sibyl become rarer and knowledge poorer by neglecting to secure all that was obtainable when she made her first or even her second offer.
